- Add more specific compatible values to the Juno R1 DT

Linaro releases contain firmware that configure

Having looked on PLDA's website it seems "PLDA" is their preferred name,
and I can't find any suffix used, so this looks fine to me:

Subject: [PATCH] x86/entry/64/compat: Document sysenter_fix_flags's reason for
existence
The code under the label can normally be inline, without the jumping
back and forth but the latter is an optimization. Document that.
Add debugfs_create_ulong() for the users of type 'unsigned long'. These
will be 32 bits long on a 32 bit machine and 64 bits long on a 64 bit
machine.

Perf will core dump if --per-socket/core -a are applied for perf stat.
The root cause is that cpu_map__build_map set refcnt of evlist's cpu_map
to 1.
It should set refcnt for the newly created cpu_map, not evlist's
cpu_map.
Here is the example:

The provides memblock_is_memory() function that
tries to find a given physical address in the memblock.memory.regions.
Let's use this function instead of direct coding of the same functionality.

Including BUG and stack dumps in commit logs makes checkpatch
produce some false positive warning messages.
checkpatch has multiple types of false positives:
o Commit message lines > 75 chars
o Stack dump address are mistaken for git commit IDs
o Link: and Fixes: lines are allowed to be > 75

Recent patches for UIO have been attempting to add MSI/X support,
which unfortunately implies DMA support, which users have been
enabling anyway, but was never intended for UIO. VFIO on the other
hand expects an IOMMU to provide isolation of devices, but provides
a much more complete device
This allows us to more easily create a "vfio" module that includes
multiple files. No code change, rename and Makefile update only.

There is really no way to safely give a user full access to a PCI
without an IOMMU to protect the host from errant DMA. There is also
no way to provide DMA translation, for use cases such as devices
assignment to virtual machines. However, there are still those users
that want userspace drivers

A recent change to the dst_output handling caused a new warning
when the call to NF_HOOK() is the only used of a local variable
passed as 'dev', and CONFIG_NETFILTER is disabled:
net/ipv6/ip6_output.c: In function 'ip6_output':

Since Yu's original e-mail I have searched all forums and bug reports

of Clock Modulation becoming enabled issues.
It is common, but particularly with some

FYI... I built this series on top of next-20151009 and using
exynos_defconfig. I booted it on my arndale, and I still don't see the
networking come up. Full boot log attached.

Hi Jeffrey & Raanan & Yanirx,
I have a Thinkpad W530 with a 82579LM inside of it, which uses the
e1000e driver. Every few hours, my system does a hard lockup, and I am
unable to do anything at all with it except power it off. There isn't
a panic or oops, as nothing is written to /sys/fs/pstore
